Enforcement of speed limitation devices (SLD) for commercial vehicles in Malaysia starts today (October 1, 2025). This will be implemented in phases to give owners and operators enough time to comply with the requirements based on vehicle category and manufacturing year, Puspakom has announced on Facebook.
SLD is a safety device within the engine control unit (ECU) that limits vehicle speed to 90 km/h. Puspakom says its role is to inspect and ensure that vehicle owners or operators submit the original SLD functional verification slip during initial and periodic inspections.
Owners of vehicles with SLDs installed by the original equipment manufacturer (OEM) must submit the SLD functional verification slip from the OEM. For vehicles with retrofitted SLDs (installed after purchase), owners must submit the SLD functional verification slip from a company recognised by the road transport department (JPJ).
Said documents must always be kept in the vehicle for enforcement purposes, and the verification must be renewed every two years to ensure the SLD is still working as intended. All parties involved in the verification must upload each vehicle’s verification slip and functionality report on JPJ’s online system as evidence, and updating must be done weekly.
Only last week, transport minister Anthony Loke revealed that a staggering 97% of the 108,805 vehicles for which SLDs are mandatory had yet to complete verification.
This is just the first phase – the second phase (from January 1, 2026) will involve SLD activation within the electronic control units (ECU) of vehicles manufactured before January 1, 2015, and the final phase (July 1, 2026) will require SLDs to be retrofitted to commercial vehicles not already equipped with them, subject to JPJ approval.

“Only last week, transport minister Anthony Loke revealed that a staggering 97% of the 108,805 vehicles for which SLDs are mandatory had yet to complete verification.”
Amazing. Good job in enforcing
Hahaha 97% yet to complete means he has failed his job as transport minister. FIRE HIM!!!
It’s not a failure but opportunity to make more money for government. Vehicle owners have choices.
Hopefully incentives will be given by gomen for companies to trade in their cancer smog inducing petrol gobbling subsidy black hole trucks for EV ones that use 1 pedal driving with minimal need for brakes. Complement this with more EV truck charging facilities. Comon Ah Loke lets do it!
The speed differential between buses travelling at 80 to 90kmh and cars wanting to travel at 110 to 120kmh on the North South Highway will create alot of frustrations and shock waves. I am already seeing such incidences . Commercial drivers who normally try to blend their speed to oncoming cars on the right lane will give up trying to do so and just let cars behind them follow on their tails albeit with alot of impatience as an overtaking manoeuvre will take much longer or even be unsuccessful to overtake and hence the commercial vehicle will just hog the right lane . A more suitable speed for buses on the NSE should be 100kmh .
